Grow lights
There are many different types of light sources used for growing plants:
- Incandescence - standard household light bulbs, low power efficiency, not much used
- Fluorescent lights - available in a wide range of spectrum's, most used industrially
- High-intensity discharge lamps (HID) - very high light power output (lumen, visible light power/flux), generates a lot of heat
- Light-emitting diodes (LED) - high power efficiency, long lifetime, good spectrum control
- High-pressure sodium (HPS/SON) - more energy in the red part of the light, promotes blooming and fruiting
- Metal halide (MH) - more light in the blue and violet parts of the light spectrum, more sunlight like, promotes plants in earlier developmental stages (growing)
